Hi Guys,
I was asked this question in an interview which I could not find and answer which the interviewer was expecting. The question is : 'I have a PS file and I just want to delete a column from that file without using any utility,sort etc. I just want to open the file and delete the column directly. How will I do it?' Can anyone tell me about this please.

I guess it is coz I never understood the question properly. He just said that you just have a PS file and you need to delete the column from it without using any utilty. I think there is some command (TSO/ISPF) by which you can do that? Does anyone know about it?

Back in 1986 when we used punch cards, each of the 80 positions were refered to as column.

This was before DB2 was a twinkle in someones eye

IIRC, DB2 was an active product in 1986 -- it dates back to the early 80's. It was based on earlier relational database work done around the mid 70's at IBM. But in 1986 I was definitely still dealing with punched cards. They were dwindling but still around then!
